Open the full vehicle complaint log (all categories)I HAD A CRACK IN THE WINDSHIELD AND WHEN THEY REPLACED IT THE TECHNICIAN SAID IT WAS SO RUSTED FROM THE INSIDE THAT IF ANYTHING HAPPENED AGAIN THEY WOULD NOT REPLACE IT HE HAD TO REALLY DO SOME WORK AROUNDS HE SAID TO EVEN REPLACE THIS ONE. THAT MAKES ME FEEL THAT THIS IS A REAL SAFETY ISSUE IF WE WERE TO GET IN A SERIOUS ACCIDENT. THERE IS NO RUST ON THE OUTSIDE AROUND THE WINDSHIELD AT ALL. SO I WAS VERY SURPRISED WHEN THE TECHNICIAN TOLD ME THAT.
SINCE ROUGHLY JUNE OF 2014 COMPLETE VEHICLE SHAKES VIOLENTLY WHEN BRAKES ARE APPLIED. I HAVE HAD IT LOOKED AT AND HAVE BEEN TOLD THAT IT IS THE BRAKE LINES ABS AND NEEDS REPLACEMENT. I AM A SINGLE FATHER OF TWO BOYS STRUGGLING FINANCIALLY AND CANNOT AFFORD NEW BRAKE LINES. I ALSO HAVE A CURRENT SITUATION WHERE THE REAR BUMPER IS COMPLETELY ROTTED THROUGH AND AS A RESULT CANNOT PASS STATE VEHICLE INSPECTION I HAVE SEARCHED FOR 2 MONTHS AND CANNOT FIND A USED REAR BUMPER AND MANUFACTURER COST IS $450-$500 WHICH I CANNOT AFFORD AT THE MOMENT. I HAVE ALWAYS HAD A GMC PICKUP AND AM VERY DISSATISFIED WITH MY PRESENT SITUATION AS I HAVE ONLY PUT 25,000 MILES ON THE VEHICLE SINCE PURCHASED. *TR
EXCESSIVE RUST THAT IS ROTTING AWAY THE FRAME OF MY 2006 GMC SIERRA. CHUNKS OF RUSTED METAL ARE FALLING OFF ON MY GARAGE FLOOR AND GMC SAYS THIS IS NORMAL CORROSION NOT COVERED. SO MUCH FOR WELL MADE AMERICAN VEHICLES. *TR
DT*: THE CONTACT STATED BEFORE PULLING A NEWLY PURCHASED VEHICLE OFF THE DEALER'S LOT, A VIBRATION WAS NOTICED. THE DEALER WAS MADE AWARE OF THE OBSERVATION AND THEY STATED THAT THE VIBRATION WAS COMING FROM THE TIRE DUE TO SITTING FOR A LONG PERIOD OF TIME IN THE LOT. THE VEHICLE HAS CONSISTENTLY VIBRATED ON NORMAL ROAD CONDITIONS TRAVELING AT SPEEDS OF 65 MPH. THE VEHICLE WAS TAKEN BACK TO THE DEALER FOR FURTHER INSPECTION. THE DEALER DETERMINED THAT THE VIBRATIONS WERE COMING FROM THE FRAME OF THE VEHICLE.
